• Defrost can start either with time and/or with temperature, depending on the settings of dF3 and dF5. If both are
enabled, then defrost will start depending on whichever happens rst.
• Defrost can terminate either with time and/or with temperature, depending on the settings of dF4 and dF6. If
both are enabled, then defrost will end depending on whichever happens rst.
• dF7 is used to override dF4 and dF6 when it’s enabled.
• dF8 is used to override dF3 and dF5 when it’s enabled.
• dF5 and dF6 will only be respected if the evaporator probe is not faulty.
• During DEFROST cycles:
• Compressor: OFF
• Condenser fan: OFF
• Evaporator fan: ON
• Heater (SubZero only): ON (if dtP is set to ACt)
• When dtP = OFF, defrost function will be disabled. When set to nAt, then defrost heater will not operate (if it was
tted), and when it’s set to ACt, then defrost heater will operate during defrost if it was tted.
• Menu item dF9 is used to determine the value shown on the display when the unit is in defrost:
• nor: Normal: The display will continue displaying values as normal.
• Frn: Frozen: The display will show the regulation probe value just entering defrost mode.
• dEF: The display will show “dEF”.
Note:
If winter mode is enabled and activated, then defrost function will be disabled until the winter mode is terminated.
8.4 VOLTAGE PROTECTION CONTROL
Parameter Description Units Min Max
UPt Enable voltage protection feature NO / YES
UHo High voltage disconnect V AC 60 300
UHi High voltage reconnect V AC 60 300
ULo Low voltage disconnect V AC 60 300
ULi Low voltage reconnect V AC 60 300
Hbt High voltage blind time Sec 0 25
Lbt Low voltage blind time Sec 0 25
Operation explanation:
• UPt: If set to No, then the rest of the parameters involved are deactivated
• UHo: If Voltage is higher than UHo for more than Hbt time, then controller is switching o all the outputs
• UHi: For allowing switching on of all outputs voltage should drop below UHi for Hbt time again
• ULo: When voltage is lower than ULo for more than Lbt time, controller is switching o all outputs
• ULi: For allowing switching on of all outputs voltage should drop below ULi for Lbt time again
8.5 DELAYS & TIMERS
Parameter Description Units Min Max
Itd Intelligent time delay Sec 0 300
Cd0 First plug-in delay Sec 0 255
Cd3 Minimum compressor OFF time Min 0 255
Cd4 Minimum compressor ON time Min 0 255
LAd Loads activation delay (delay between consecutive loads to come ON) Sec 0 255
Cd5 Maximum compressor ON time without temperature drop before initiating
a forced defrost (with possible initiation of refrigeration fault mode)
Hrs N/A, 1 50
Cd6 Maximum compressor ON time without temperature drop before initiat-
ing refrigeration fault mode
Hrs N/A, 1 50
dCO Compressor on-cycle duration when regulation probe is faulty - DAY mode Min N/A, -40 90
dCF Compressor o-cycle duration when regulation probe is faulty - DAY mode Min 1 255
nCO Compressor on-cycle duration when regulation probe is faulty - NIGHT
mode
Min N/A, -40 90
nCF Compressor o-cycle duration when regulation probe is faulty - NIGHT
mode
Min 1 255
Operation explanation:
• On rst plug-in of the cooler, loads must be activated after “Cd0” has elapsed, and after “Itd” has elapsed too for the
compressor to come ON.
• Timer “Itd” is reset every time the compressor relay switches OFF, and it will not allow the compressor to come ON
until this delay is over. This is Intelligent Time Delay with time-save feature - if the JEA unit has been OFF for longer
